Isoform switch of pyruvate kinase M1 indeed occurs but not to pyruvate kinase M2 in human tumorigenesis. [PDF]

PLoS ONE, 2015
Muscle type of pyruvate kinase (PKM) is one of the key mediators of the Warburg effect and tumor metabolism. Due to alternative splicing, there are at least 12 known isoforms of the PKM gene, of which PKM1 and PKM2 are two major isoforms with only a 23 ...

The role of fibroblast growth factors in cell and cancer metabolism

FEBS Letters, EarlyView.
Fibroblast growth factor (FGF) signaling regulates crucial signaling cascades that promote cell proliferation, survival, and metabolism. Therefore, FGFs and their receptors are often dysregulated in human diseases, including cancer, to sustain proliferation and rewire metabolism.

A monomeric form of pyruvate kinase in human pyruvate kinase deficiency. [PDF]

Proceedings of the National Academy of Sciences, 1977
A mutant pyruvate kinase (ATP:pyruvate 2-O-phosphotransferase, EC 2.7.1.40) from human erythrocytes which is easily separated into monomers and dimers by gel chromatography is described. Tht mutant enzyme shows almost the same pH optimum and thermostability as normal enzyme, but has a decreased stability on shaking with air, a decreased Km for ...

Cardiosphere-derived cells demonstrate metabolic flexibility that Is influenced by adhesion status [PDF]

, 2017
Adult stem cells demonstrate metabolic flexibility that is regulated by cell adhesion status. The authors demonstrate that adherent cells primarily utilize glycolysis, whereas suspended cells rely on oxidative phosphorylation for their ATP needs.

Inhibition of CDK9 enhances AML cell death induced by combined venetoclax and azacitidine

Molecular Oncology, EarlyView.
The CDK9 inhibitor AZD4573 downregulates c‐MYC and MCL‐1 to induce death of cytarabine (AraC)‐resistant AML cells. This enhances VEN + AZA‐induced cell death significantly more than any combination of two of the three drugs in AraC‐resistant AML cells.

Cysteine catabolism and the serine biosynthesis pathway support pyruvate production during pyruvate kinase knockdown in pancreatic cancer cells

Cancer & Metabolism, 2019
Background Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with limited treatment options. Pyruvate kinase, especially the M2 isoform (PKM2), is highly expressed in PDAC cells, but its role in pancreatic cancer remains controversial.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

The LytS-type histidine kinase BtsS is a 7-transmembrane receptor that binds pyruvate

mBio, 2023
LytS/LytTR-type histidine kinase/response regulator systems regulate crucial host-specific mechanisms during infection of human or plant hosts. Escherichia coli has two of them, and the histidine kinase BtsS is a high-affinity sensor for extracellular ...
